The Mayflower has a famous place in American history as a symbol of early European colonization of the future United States.(http://en.wikipedia.org/wiki/The_Mayflower).

A science improvement, and hence what Spain called the New World, which is now The United States of America. (http://tmscconsultingsvcs.wordpress.com/2010/09/10/what-caused-columbus-voyages/).
